Sound Level and Intensity Meter using Sound Sensor & Arduino

In this video, we have interfaced the Arduino sound module with Arduino and 16*2 LCD for designing a simple decibel meter for measuring the sound level and intensity. The module is capable of measuring the sound intensity and loudness levels. The programming is done on the basis that whenever the sound is not detected, it displays sound level as zero value.  The value of sound level ranges from 0 to 1000 or more. low-level intensity is considered as 0-50, medium as 0-500, and high as above 500. On a high level, the red LED glows indicating the sound is too high.
